PIPING.

SPECIFICATION forming part of Letters Patent No. 285,850, dated Octobenf, 1883.

Application led March 19, 1883. (No model.)

To @ZZ whom it may concern:

Beit known that I, SAMUEL S. SPEAR, of South Weymouth, county of Norfolk, State of Massachusetts, have invented an Improve` ment in Piping, of which the following description, in connection With the accompanying drawings, is a specication, like letters on the drawings representing like parts.

This invention relates to piping having a folded' or round edge and a snipped edgesuch, for instance, as shown in United States Patent No. 270,965, to which reference may be had.

The object of the invention is to enable the tongues at the snipped edge to override each other readily and uniformly when the piping is so bent that the folded edge is longer than the snipped edge.

My invention consists in a folded piping as an improved article of manufacture, it having one edge snipped diagonally, as will be described.

Figure l represents in side view and crosssection a piece of piping embodying my invention; Fig. 2, a view of the snipped edge; Fig, 3, a side View of a piece of my improved piping bent to show the position of its tongues; Fig. 4, an edge view of the snipped edge on a small curve, showing the tongues as overriding; and Fig. 5, a view showing the tongues drawn one away from the other, as when the snipped edge is longer than the folded edge.

My improved piping is composed of a piece of leather folded upon itself, as shown in Fig. l, with the grain face outermost, so as to form a folded edge, a, the parts of the strip so brought together being united by suitable or usual paste or cement, and slotted at 2 to form tongues b b, to enter between the two edges of shoe-uppers, as usual.

In the patent referred to the inner edge of the piping was snipped, instead of being notched or cut out, as had been previously practiced. In this my present invention, in-

stead of cutting the inner or rear edge of the piping through from side to side at right angles to the length of the folded edge, as therein practiced, the said edge is cut through diagonally, as shown at 2, Fig. 2, leaving tongues b b, so that the contiguous edges of the said tongues are beveled or inclined in the same direction and lap one over the other. When the piping is to be folded on such a curve that the folded edge a is to be the longest, the -tongues b b easily and readily ride up one over the other, as at the central part of Fig. 3 and in Fig. 4, enabling the piping to be bent to conform to the smallest curves without puckering. O11 the contrary, when the folded edge is to be the shortest and the snipped edge the longestyas represented by the tongues b2, Figs. 3 and 5, the beveled edges of the tongues ride down one over the other, but do not separate so far as to leave an open space between the tongues, as would be the case if the slits were not beveled from side to side.

The beveled edges of the tongues enable the piping to be readily and easily bent into any desired curve without bunching, and the edge formed by the tongues to be kept of more nearly uniform thickness than heretofore.

In Fig. 2 the line 3 represents the junction of the superimposed pieces of leather entering into the piping. In Figs. 4 and 5, where the snipped edge is represented, respectively, as inwardly and as outwardly curved, the short lines 3 indicate the changed position of the tongues.

I claiml K Y As an improvedv article of manufacture, a folded piping having one edge snipped to form tongues with beveled contiguous edges, to operate all as and for the purpose described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
